Your Answer for Question 1:
when malloc is called and the chunk of the free block is too big, then the malloc will only point to a portion of the big block and return the space that is not being used.
So b is correct.

Your Answer for Question 2:
If the block to free is at the end of a list, the freeblock will be combined with the list and leave the number of free blocks unchanged.
So b is right.
The space freed is automatically combined to create a new block, so when a block is freed it may reduce the number of free blocks at the most by one (when the block to free is between two free blocks).
so c is right.

Your Answer for Question 3:
new
delete
It is impossible for the C to determine whether the piece of memory is no longer needed or not. 

Your Answer for Question 4:
It won't work with reference count method, because by using this method, the computer simply won't count things that are pointing to null.

Your Answer for Question 5:
memory management, especially things in the notes.
